I think all foil is lovely! My worry would be that if there are misalignment issues with a mix of foil and non-foil dots, then they may be much more noticeable with the B option that if they are all done in foil. Best of luck!

I like them both, but chose A. The idea of mixing up the dots with black is interesting, but I'm not sure of the balance you have. If you want to go that route, what about somehow having some black dots on the top and bottom of both sides?
